Specification of l etters Patent.

Patented April 7, 1908.

Application flied July 12, 1907. Serial No. 383,541.

7 '0 all whom it may concern:

Be it known that I, ISIDOR KrrsEE, citizen of the United States, residin at Philadelphia,

'. 1n the county of Philadelphia and State. of 6 Pennsylvania, have invented ce'rtainnew and useful Improvements in Electric Transmission of Intelligence, of which the following is i Y asplecification.

y invention relates to an im rovement in the electric transmission of intelligence. Its

object is, to neutralize the'impulses induced in lines of transmission from neighboring 7 wires.

The drawing represents in diagrammatic vlew'lines of transmission, an inducing line and means to neutralize the impulses iii- -duc ed in, said transmitting lines.

I have illustrated this, my invention, asbemg applied to lines of transmission inthe inducing region of a ower wire used for electric pro ulsion an I have, therefore, illustrated t e return as to consist ofthe rails of travel.

In this drawin 1 is the power wire; 6 the rails of travel. hese rails of travel act as the return. I-have not illustrated the conemotion of the generator as to the wire 1 or to the rail 6, as such connection iswell under stood, but it is supposed that these rails 6 act as the return of the wire 1.

-2, 3 and 4 are liiies of transmission, either telegra hic or telephonic. In roximity to i 6 is the"'conductor 5. his conductor may consist of an insulated wire buried or placed otherwise near said rail, so as to be in the inductive field of same. The line 2 is connected here with the interposition of condenser 9 and inductive resistance 15 on one side and through condenser 12 and inductive The line, 3 is connected throughcondenser 8 and inductive resistance Mend condenser 11 and inductive resistance 17, .to wire 5. The line 4 is'conneotedto ire 5 through condenser's 7 and 10 and inductiverrpsi stances 13 I: i

'andilS.

When, through the flow of an alternating or phase current, an impulse is indu. in lines'2, 3 or 4, an impulse flowin in the l nposite direction is simpltaneousily inducelit in wire 5. This impulse 'is of a direction. op- I in the line from the power wire proper.

resistance lfi on the other side, .with wire 5.

any of the lines of transmission are. not of a like intensityas the same are not in a like relation to the wire 1, it is obvious that, means should be provided, so as to -regulate .60 the flow of the impulses from 5th any of these lines of transmission, and I haveshown the condensers and inductive resistance as such means. d

In the practical operation of this-system, the condenser as well as the inductive re'- sistance, should have means so as to vary their value. The erson in charge when connecting one orv t e other of the lines to; the wire 5, should adjust the capacity of theggfo condenser and resistance of the inductance, v so that the impulse from 5 should be just 'suflicient to neutralize the impulse induced It is well knowntthat in practice th lines .75;

of transmission, that is, the telegra hicor'h telephonic wires, are carried further t an they power wires and it is only necessary to counrfl, tor-balance, so to speak, the inducin effect of these lines for the distance" that t ey meson, in the region of these power wires. f

Having now described my invention, whatQ-: I claim asnew and desire to secure by Let: ters. Patent is 1. Means to neutralize impulses"induced s in lines of transmission .from neighboring Fin,

wires, said means com rising a conductor in. inductive relation to t e return-of said wires and adjustable means to connect said con-,1; ductor to two or more of said lines of trans w mission. p 2. A series of linesof transmission, a come mon conductor for same, and means to con nect said lines of transmission to said com-Q mon conductor, the lines of transmission in '95;

the inducing field of a ower wire and the common conductor in tlie inducing field of the return-for said power wire. v p 1 3. In combinationwi h one or more lines.

of transmission, positioned in the inducing 1m region of a power wire, means to neutralize the inducing effect of said powerwire said means comprising a shunt for-part oi said" 1' lines of transmission, the shunt-wire in the inducing region of the return for said power: or

wire.

In testimony whereof I affix my signature inpresence of two witnesses.
